The present disclosure relates to a biologically active biomatrix composition. In one embodiment, the biomatrix composition is derived from human amnions. The biomatrix is termed HuBiogel™. The composition of HuBiogel™ closely mimics naturally occurring basement membrane compositions and is capable of supporting a wide variety of cell types in vitro and in vivo. The HuBiogel™ biomatrix disclosed comprises, in one embodiment, laminin, collagen I, and collagen IV, and may further comprise any combination of the following: entactin, tenascin, fibronectin and proteoglycans. The biomatrix composition is essentially free of endogenous growth factors and proteolytic enzymes. Also described are two- and three-dimensional culture systems and physiological/pathological model systems utilizing the HuBiogel™ compositions. The HuBiogel™ compositions may be modified to contain desired growth stimulants, such as growth factors, polypeptides and organic mall molecules, and may also contain growth inhibitory agents and/or therapeutic agents. |
